It takes a lot to surprise True Blood fans, but Sarah Newlin (Anna Camp) kissing the severed head of her late lover, Gov. Truman Burrell (Arliss Howard), in last week’s episode did it. ”I had no idea, actually, that I was gonna kiss the head, it just sort of happened,” Camp said in an interview with Entertainment Weekly managing editor Jess Cagle that aired this week on EW’s Sirius XM channel. “If I get an impulse that’s, like, creepy, I’m like, why not? They can always tell me not to do it. But better to be pulled back than to be pushed forward, you know.”

But here’s something even more shocking: Sarah Newlin’s most insane moment is still to come. The Aug. 4 episode will feature a sequence shot over three days that the Pitch Perfect actress refers to as “the craziest scene I’ve ever shot.” She ended up going to the emergency room – in full Sarah Newlin hair and makeup – for a minor injury she received doing a stunt. Listen to the interview below for more.

The interview will replay on Sirius XM’s Channel 105 several times this weekend; visit EW Radio’s website to find out when.
